Abstract

OBJECTIVE:

To investigate the role of cervical muscles in cervical spondylosis according to the changes of radiology findings and strength cervical extension muscles between cervical spondylosis patients and normal people, in addition, to evaluate the effect of patients with cervical spondylosis treated with nonoperative therapy and rehabilitation.

METHODS:

The experiment was performed at the Yueyang Hospital of Integrated Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine and Massage Laboratory of State Administration of Traditional Chinese Medicine from December 2005 to November 2008. Sixty-three patients with cervical spondylosis were randomly divided into massage and traction groups, other 30 normal people were served as the control group. The differences of incidence rate of unstable segments, position of unstable segments was compared between patients and normal people, more over, the vertebra displacement and strength of cervical extension muscles after 2 weeks in the massage and traction group was observed.

RESULTS:

① Compared with normal population, the number of cervical segments instability and the cases in several segments were significantly increased. ② After treatment, the number of cervical segments instability and the cases in several segments were significantly reduced in the massage group. ③ Compared with the normal population, Patients with cervical spondylosis, neck extensor and flexor peak torque (PT), active muscle/antagonist muscle ratio (F/E) was significantly reduced at 60 ° /s kinetic exercise. ④ After treatment, PT and the active muscle/antagonist muscle ratio was significantly improved in the massage group.

CONCLUSION:

The characteristics of cervical extension muscles contributed to the prevalence of cervical spondylosis. Cervical muscles play an important role in treating cervical spondylosis without operation.
